' 3,128/ 66 Int. Cl. B65d 91/00 U.S. Cl. 232-1 1 Claim ABSTRACT OF THE DISCLOSURE A chad receptacle is provided containing an internal structure to limit the height of a cone-shaped pile of chads, after which the chads can overflow into the remainin-g portion of the receptacle. The receptacle may also have a chad outlet so that the overowing chads drop out as a warning to empty the receptacle.

This invention relates to receptacles for the cuttings or punchings from perforating or punching machines. Such cuttings or punchings are commonly known as chads and will hereinafter be referred to as such.

The disposal of chads from perforating machines has for a long time presented a problem because:

(a) Due to the presence of wax, oil or static charge, they tend to stick together and do not readily ilow.

(b) They pile up in a conical formation and do not use the whole of the capacity of the chad receptacle or cutting box.

(c) If the box is not emptied frequently enough the cone can block the end of the chad outlet chute and jam the mechanism, and

(d) The chads may overflow into the mechanism.

It has been the practice with telegraph reperforators to adopt a routine of emptying the box whenever reloading a fresh reel of tape. It is not practicable to employ this routine on high speed tape punches, as standard 1000 foot reels of tape can be consumed at a rate of one every seven minutes.

It is desirable to employ a routine of emptying the box at the beginning of each eight hour shift, but because the chads pile up in a cone, a box of larger capacity is needed.

If the chads can be made to spread then the size of the box can be reduced. Furthermore, at the present time there is a requirement to provide a warning that the cuttings box needs emptying, either by visual or audible means, or by allowing the chads to emerge from the machine and spill onto the licor, and not into the machine.

Since paper chads punched out by a reperforator tend to pile up in the chad receptacle in a cone-shaped pile, the tip of the pile can block the chad chute. Therefore, according to the invention there is provided a chad receptacle containing a sloping wall with an opening near its top to limit the height of the cone-shaped pile, so that the chads overflow into the remainder of the receptacle. The receptacle may also contain a chad outlet so that the overowing chads drop out as a Warning to empty the receptacle.

Two embodiments of the invention will now be described with reference to FIGS. 1 and 2 respectively of the accompanying purely diagrammatic drawings.

y United States Patent O 3,454,215 Patented July 8, 1969 ice Referring to FIG. 1, a receptacle in the form of a box 1 has suspended within it a frusto-conical enclosure 2 which is open at its top and bottom. The aperture in the narrow upper end is disposed beneath an outlet chute 3 for chads coming from the punching mechanism. Because of the enclosure 2, the chads 4 falling from the outlet chute 3 are first constrained to pile upin a conical formation of a predetermined height as indicated by the broken lines 5. Thereafter, the chads overflow and pass down the exterior of the sloping walls of the enclosure 2 and pile up in the remainder of the lbox as shown at 6, so making the maximum use of the box and ensuring that the tip of the conical pile cannot enter the outlet chute 3.

Turning to FIG. 2, the box 7 has within it an enclosure of triangular section formed between adjacent sides of the box and a sloping wall 8. The latter has an aperture near its upper end disposed beneath the chad outlet chute 3. Because of the enclosure thus formed, the chads 9 falling from the outlet chute 3 are first constrained to pile up in a conical formation of a predetermined height as indicated by the broken lines 10. Thereafter, the chads overflow and pass down the exterior of the sloping wall 8 as shown at 11. Obviously, they could then be allowed to pile up within the remainder of the box but, in accordance `with a feature of the invention, they are allowed to leave the box by way of an aperture 12 adjacent the bottom of the wall 8 and thus to fall on the oor. This gives a warning that `the box needs to be emptied and, at the same time, prevents the overflowing chads from interfering with the punching mechanism, as in the previous embodiment, the tip of the conical pile of chads does not reach the bottom of .the chute 3 and cannot, therefore, block it.

It is to be understood that the foregoing description of specific examples of this invention is made by way of example only and is not to be considered as a limitation on its scope.

What I claim is:

1. A box-like chad receptacle having Within it an apertured enclosure which is triangular in cross-section and is formed by adjacent vertical box sides of the receptacle and a sloping wall extending between said sides, said sloping wall having an aperture near its upper end `beneath a chad outlet chute, so that chads falling from the chute pass through the aperture to pile up Within the enclosure in a conical formation to a height determined by said sloping wall, after which the chads overflow and pass down the exterior of the sloping wall and an aperture in the box-like receptacle adjacent the bottom of the sloping wall whereby the overflowing chads can leave the receptacle to give a Warning that the enclosure needs to be emptied.
